err well, ((42 - 16) * 1)

I heard it used in a game of Darts. Thrower got a 5, a 20 and a 1. His opponent is was born and raised in, as he put, on the low side of London.

He was barely understandable. But the "Bed and Breakfast, you trying to (unintelligible mumble) me?" was more understandable.

But, I looked it up today to confirm the score was 26.

Then I also saw it being a 2 and 6 in regard to lodging and meal costs long ago. I didn't know that. But it does make sense.
